Detailed ways

In order to deepen the understanding of the utility model, the utility model will be further described below in conjunction with the examples, which are only used to explain the utility model, and do not constitute a limitation to the protection scope of the utility model.

As shown in Figures 1, 2, 3, and 4, this embodiment provides a conical friction disc automobile clutch, including an active part that is directly fixedly connected with the engine, a driven part that transmits power by frictional contact, and a control active part. The compression mechanism is partly in contact with the driven part, and the driven part and the compression mechanism are arranged inside the active part.

Specifically, the active part includes a flywheel 2, a clutch housing 7 fixedly connected with it by screws 10, and a pressure plate 3 inside it. The driving part, the driven part and the pressing mechanism are all coaxial or installed or distributed on the first shaft 5 of the transmission.

The driven part includes a driven disc assembly 1 and friction plates 4 fixedly installed on its front and rear surfaces. The driven disc assembly 1 is provided with a torsional shock absorber 13 .

The pressing mechanism is mainly a diaphragm spring 9 with an elastic effect.

The end of the diaphragm spring 9 is rotatably connected with the pressure plate 3 through the release hook 8, and the middle part is riveted together with the clutch housing 7 by several diaphragm spring rivets 11. The front portion of the diaphragm spring rivet 11 is provided with an automatic compression spring 12, and the corresponding part of the clutch housing is provided with a ring protrusion 71.
